If you receive an error stating that we failed to authorize the card, this means the credit card issuer declined the authorization. The most common reasons for failure include:

Address verification (AVS) mismatch

Invalid CVV/Expiration

Card is flagged as lost or stolen

Risk or fraud decisions from the issuing bank

When a card fails authorization, we recommend having the payer verify the card information then entered, and if that is all correct, having them reach out to their card issuer to verify their billing information and attempt the payment again.
